The remote Debian 11 host has a package installed that is affected by a vulnerability as referenced in the dsa-5405 advisory.
OIDCStripCookies
is set and a crafted cookie supplied, a NULL pointer dereference would occur, resulting in a segmentation fault. This could be used in a Denial-of-Service attack and thus presents an availability risk. Version 2.4.13.2 contains a patch for this issue. As a workaround, avoid using OIDCStripCookies
. (CVE-2023-28625)Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- mod_auth_openidc is an authentication and authorization module for the Apache 2.x HTTP server that
implements the OpenID Connect Relying Party functionality. In versions 2.0.0 through 2.4.13.1, when
`OIDCStripCookies` is set and a crafted cookie supplied, a NULL pointer dereference would occur, resulting
in a segmentation fault. This could be used in a Denial-of-Service attack and thus presents an
availability risk. Version 2.4.13.2 contains a patch for this issue. As a workaround, avoid using
